MIKE PERSECI-I, OF WALSEN, COLORADO.

COAL-LOADING- MACHINE.

Application led April 6,

To all whom t may conecta' Be it known that I, Minn Pressen, a citizen or the United States of America, residing at VValsen, inthe county of Huerano and State oi Colorado, have invented certain new and useful Improvements in Coal-Loading ivlachines, of which the following is av specification.

The primary object of the invention is the provision of a machine adapted for loading shattered coal from the working vface ot a mine wall int-o the pit cars for removal 'from the mine, the opeiation oi the machine being rapid and easily controlled by a single operator.

A further object of the invention -is the provision ot a machine serviceable in a coal mine for quickly loading large quantities of coal upon the pit cars whereby one machine I operated by a'single man will load the coal quicker than a small gang of men, thereby econoinizing both time and expense.

A still further object of the invention is the provision of a mining machine which is motor-driven adapted 'for approaching in close proximity to a aile of coal Afor attacking the saine and drawing the coal in consi derable quantities upwardly and away from i in Figure 13,

the pile ior deposit in pit cars positioned for transporting the coal to a distant point.

VJ ith these general objects in view the invention consists of the novel combination and arrangement of parts hereinafter more fully described in connection with the accompanying drawings and in which like reierence characters designate corresponding part-s throughout the several views.

In the mining of coal it is usual to blast the tace of the mine tor shattering the wall and then employ unskilled labor for loosening the coal with picks and carting the same away for deposit in the pit cars. My mallo the operation/of gathering up the coal, elevating it above a car, and droppingfthecoal into the car being quickly accomplished in the manner hereinafter described.

1n Figure 1 of the drawings, a view in a coal mine is shown having' a track 10 running perpendicular to the working face or wall 11 of the mine, a pile 12 of loosened coal being shown at the base of the wall 11 with my machine mounted upon the track illustrated in the act of gathering coal from the pile 12 for deposit in the pit car 13 running upon the track 10.

My machine includes a platform 14 in the form of platform car having its wheels 15 upon the track 10, the `said wheels being driven by a motor 16 mounted upon the platform. A. main power shaft 17 extending transversely of the platform 14 is operatively connected to the motor 16 by gears 18. The axles 19 of the wheels 15 are connected by sprocket chains 2() with clutch members 21 freelyjournaled at theopposite ends of the shaft 17. Clutch members 22 adapted to cooperate with the members 21 areslidably splined upon the shaft 17 with operating` levers 23 and 24fvof theconstruo tion shown in Figure 12. A handle 25 upon the free end of the. lever 24 is positioned at one side of the platform 14 for convenience in opening and closing the clutches 21-22 simultaneously for imparting movement to the platform car just described. The motor 16 is of the reversible type permitting the platform car to be propelled in either direction upon the track 10, a suitable controller 26being arranged for the motor 16 to govern the speed and direction of movement of said motor.

A mounting section 27 herein referred to as secti'ounumber 1 of the machine frame is adjustably supported upon tne platform 14 by a plurality of saddles 28 operated by j ack screws 29 and with transverse depending ribs 30 of the section 27 positioned in the said saddles 28. This adjustable manner of n'ifnlnting section 27 upon the platform car is illustrated in Figure 8 of the drawings, an adjustable brace 31 being pivoted as at 32 to each side 33 of the platform'14 with an adjustable' screw portion 34 pivot-ed at 35 to one side 36 of said mounting section 27. By adjusting the jack screws 29 and. the screw 34, the inclination Vof the mounting section 27 is readily controlled and rigidly held at the desired adj us tment.

A forwardly curved and downwardly inclined sheet metal plate 37 forms the front nose of the machine and is called a nose plate, being designed to be pushed into the loosecoal 12 during the forward. movement of the machine when positioning the same for the gathering operation. Side wings 38 are pivoted as at 39 to the plate 37 while foidable braces 40beneatlrthe.wings normally retain the wings in4 outstretched posi- .tion at .the oppositeisides of the plate 37.

An intermediate section 41 termed section No. 2 consists of parallel sides 42 with side ledges 43 forming a' continuation of similar ledges 44 of the sides 36 of section No. 1. Sections Nos. 1` and 2 are pivoted together by a rod 45 carried by section No. 1 and extending through slots 46 in the sides 42.

A further section of frame 47termed ysection No. 3 is positionedat the rear of the machine with its forward end connected to the rear end of section No. 2. Section r47 consists of a rear cross beam 49 and side members 50, the latter member being attached by brackets 112 to the rear end 48 of section No. 2. The members 50 are oppositely beveled on theirupper'sides as at 51, forming a bearing surface for employing the sidemembers 50 asztrack rails. Adjustable roof braces 52 are mounted upright on the floor of the mine being. suitably attached at 53 with the opposite ends of the beamv 49 for supporting the rear end of themachine while an adjustable screw 54 4in the upper end of L'each brace 52 engages the mine roof55.

A frame member 56 shown in Fig. 14 has side rails 57 normally positioned for sliding upon the flanges-4.4 and between the sides 36 of section No. 1. The frame member 56 is capable of rearward movement for sliding upon the flanges 43 of the sides 42 of section No. 2, thefmovement of said frame member 56 being to and fro from its` forward position upon section No. 1 as illustrated in Figures 1, 27 3 and 8 of the drawings, and its rearward position upon section No. 2, as shown in Figures 4 and 5 thereof. Jrbottomslide 58 illustratedin Figure 15is mounted by meansY of rollers 59 upon track rails 60 longitudinally carried by the frame'member 56, the rearward movement offthe bottom 58 being continued upon the track 50 of the rear scction No. 3,.after the framemember 56 has assumed vits rearward position upon section No. 2, during the delivering and dumping operation., A foldable scoop 61 illustrated in Figure 18 is normally slid-ably mountedv upon opposite ledges 62 of the sides 57 of theframe member 56 and consists of shovel-shaped side sections 63 centrally hinged together `at 64 at the rear end of the scoop. The scoop 61 being normally mounted in the vframe member 56 willfmove forward into thepile of coal 12 as illustrated AinfFigiuSes 1 and'2 of the drawings and is then capable of retracting` rearwardly with a quantity of coal, the Scoop 61 taking its position with the coal upon the bottom slide 58 and whereupon the frame section 56 with the slide 58 and the filled scoop 61 will be propelled rearwardly kugon section No.2 of the frame. The slide bottom 58 will then be movedv rearwardly upon section No. 3.permitting the coal in the scoop 61 to drop through the frame member 56y and section No. 2 into the pit car 13 provided upon the track 10 beneath said intermediate section No. 2. After unloading,` the load of coal in this manner, the slide 58 is returned to the track 60 of frame member 56, it being noted that the scoop 61 remains upon the ledges 62 of said frame member 56. The frame member 56 is then forcibly moved forwardly and downwardly of section No.2 and section No. 1 carrying'the slide 58 and scoop 61 therewith until the frame member 56 and the'slide 58 reach their normal positions upon section No. 1 as shown in Figure 3, the scoop 61 continuing its forward lmovement and automatically opening with its side 63 projected into the coal pile 12.

The forward edge 64 of the slide 58 has abutting` engagement with the rear edge 65 of the plate 37 when said slide 58 is in its ynormal forward position as -illustrated in Figure 8. Curved defleotors 66 at the forward end of frame member 56 project over the side wings 38 assistingin giving' direction and closing movement to the scoop 61 during its rearward travel when the frame member 56 is at the forward limit of its move-V ment. rl'he sides 57 of the frame member 56 are cutaway as at 67' permitting` the deflectors 66 to ride over the sides 36 of mounting section 27. y

Metal cables 68 are attached adjacent the rear end of the frame member 56 to the sides 57 thereof as at 69 and pass rearwardly of the machine over pulleys 70 upon the rear cross beam 49 of section No. 3. The cables 68 then pass beneath section No. 3 and sect-ion No. 2, forwardly above the platform 14 to the inwardly positioned grooves 71 of double grooved pulley wheels 72 freely journaled upon the powershaft 17. Similar cables 68 are attached adjacent the forward ends of the sides 57 of the frame member 56 as at 73 and pass formirdly through perforations 74 in the forward plate 37 and over rollers 75 in thc rear sides of said perforations`r the cables 68 thence passing' to the outer sides or grooves 76 of said wheels 72. Clutch meinbers 77 slidably splined to the power shaf 17 are adapted for simultaneous clutching engagement with the pulley wheels 72, similar angular levers 78 being provided for each shiftable clutch member 77 with handles 79 and 79 upon the free ends of the levers 78 adjacent the clutchoperating handle 25` When the clutch handles 7 9, 7 9 are moved in opposite directions for closing;` the clutches 77.` the wheels 72 will revolve with the shaft 17 in whichever direction the motor 16 is operating and thereby the cables 68 will be wound upon the wheels 72'while the cables 68 are being unwound or vice versa. The

. winding` up of the cables 68 pulls the frame member rearwardly` the movement thcref of being' limited to its rear position upon section No. 2, The reverse rotation of the shaft 17 winds up the cables 68 thereby pull ing the frame member 56 forwardly lo its normal position upon section No. 1.

In a similar manner, cables 80 are at tached as at 81 to the rear end of the slide 58 and pass to the rear of the machine over pulleys 82 upon the rear beam 49, the cables 80 then passing beneath the machine sections N o. 3 and No.. 2 and above the platform 14k beneath the section No. 3 to the inner grooves 83 of pulleys 84 journaled upon the powershaft 17. Similar cables 80 are attached to the under side of the slide 58 adjacent its forward edge 64 as at 85 and pass forwardly over pulleys 86 beneath the asl shown in Fig. 5, the springs 91 upon the rear edge of the slide 58 engage resilient hooks 92 upon the rear cross bar 49 of the machine assisting to retain the slide 58 upon section No. 3, until forcibly drawn forward by the cables 80 when the motor 16 is reversed.

Cables 93 pass through the sides 63 of the scoop 61 having' knots or buttons 94 for enpaginal inwardly of the rear end members 95 of the scoop 61, the cables 93 passing rearwardly over sheaves 96 on the outer sides of the members 4t2 and forwardly over pulleys 97 on the defiectors 6b and through perforations 98 in the plate 37. The cables 93 pass over rollers 99 in the perforations 98 and thence beneath the plate 37 to the outer grooves 100 of pulley wheels 101 journaled upon the shaft 17. The turning' of the shaft 17 inr the direction indicated by the arrow in Fig: 6 winds up the cables and rearwardly moves the scoop 61. The forward end portions 93 of the cables 93 pass forwardly through similar perforations 102 in the plate 37 and thence beneath said plate to the inner groove 103 of the wheels 101. The reverse operation of the shaft 17 when operating the pulleys 101 winds up the cable portions 93 and pulls the scoop 6l downwardly toward t-he plate 37. During the downward and forward movement of the frame member 56, the slide 58 and the scoop 61, the frame member and slide will stop upon the machine section 1 while the scoop 61 will (ontinue its movement by reason of 'its own momentum and the pulling cable sectfio'1i-s'93 until the scoop 61 moves `over the` 'plate 37' andautomatically assumes an open position by reason ofthe fact that'the cable i portions =93 act aS-' anchors forthe i scoop side 63 causing" 1elat1vemovement upon the hinge (64.' The operator vmay scoop (31 in'thecoal pile 12 fory recei'i'fing a suitable load'.
